Embodiment Construction
[0027] exist Figure 1 to Figure 4 Shown above is a trolley 1 for storing and distributing dinner plates in a hospital environment, the trolley is capable of keeping a portion of these plates warm and another portion of these plates cold, which is useful in dispensing the plates. given to the patient throughout the period.
[0028] The trolley 1 consists of a rectangular load-carrying frame 3 mounted on wheels 5 and supporting a structure forming a double carriage 7 accessible from opposite doors 9 . Each of the two carriages 7 is separated lengthwise by an insulating wall 11 to form a compartment 12a called a "hot food compartment" on one side and a compartment 12a called a "cold food compartment" on the other side. "A compartment 12b.
[0029] The plates 13 are stacked and slidably mounted on plate racks inside these hot and cold food compartments, so that one part 13a of each plate is arranged in the hot food compartment 12a and the other part 13b is arranged in the cold ...

Abstract
The present invention relates to a self-contained trolley for temperature conditioning and distribution of meal trays (13) comprising two compartments separated by an insulating wall (11), namely a compartment for heating, called the hot compartment, and a compartment for chilling, called the cold compartment, receiving at least one stack of meal trays arranged so that one part of each meal tray (13) is located in the hot compartment and the other part thereof is located in the cold compartment, wherein the heating of the hot compartment and the chilling of the cold compartment are simultaneously obtained by means of a thermochemical system. This trolley is characterised in that said reactor (15) and the evaporator of the thermochemical system are respectively and exclusively arranged in the hot compartment and in the cold compartment and in that the reactive material used in the thermochemical system consists of a compacted mixture of manganese chloride and expanded natural graphite (ENG), and the gas consists of ammonia.
Description
technical field [0001] The invention relates to a trolley, in particular for distributing dinner plates and setting the temperature of the food contained on them. Background technique [0002] In the field of restaurants and in particular in the field of restaurants in hospital environments there are trolleys in which it is necessary to keep warm food for hot food, such as in particular soups, meat and vegetables, and for cold food. Food – such as especially certain first courses, cheeses and desserts – is kept warm. [0003] In the prior art and in particular in the patent document US 4.974.419 it is proposed to use storage cabinets equipped with heating and cooling elements and allowing the food they contain to be kept warm separately before being distributed to beneficiaries and refrigerate. Systems are thus proposed that include, for example, an electric resistance to provide the heat required to keep food that should be served hot, and components such as a compressor ...
